Building on top of > that may give users of tcmu a better experience. s/tcmu/tcmu-runner/ I don't think there are separate tools/utils for tcmu-runner as of now. Also currently we are using tcmu-runner to export the file in the gluster volume as a iSCSI block device, in the future we may move to qemu-tcmu (which does the same job of tcmu-runner, except it uses qemu gluster driver) for benefits like snapshots ? Also configuring and running tcmu-runner on each node in the cluster for multipathing is something not easy (take the case where we have more than a dozen of node). If we can do these via gluster CLI with one simple command from any node, we can configure and run tcmu-runner on all the nodes. > > If you can add such a consideration in the feature page, I'd appreciate > it.
